[Stk] New STK release (4.4.0)

[Gary Scavone]

Hi John,

If you look at the Md2Skini.cpp code, you'll see that SKINI messages  
sent to stdout always have a delta time of zero.  This is because in a  
realtime context, a delta time of zero say "apply the message  
immediately" (which is usually what one wants).  However, if the  
output is sent to a file, the delta times are not zero ... they are  
the actual times between events.

I guess it would help to say that in the usage statement!

Regards,
